White phosphorus (P4) is a critical element in industry, but its current production from phosphate
rock using the carbothermal reduction method raises significant environmental and health concerns.
This pressing issue necessitates the development of new technologies that facilitate the sustainable
production of P4. In response, my team is actively developing an innovative, coke-free approach for
white phosphorus production. This method involves the dissolution of phosphate rock in molten
CaCl2, followed by the extraction of P4 through electrochemistry at relatively low temperatures.
Moreover, this approach has the potential to utilise phosphate-bearing solid wastes as raw materials,
further enhancing its environmental benefits. By employing this cutting-edge technique, we aim to
revolutionise the phosphorus chemical industry towards greener and more sustainable practices.
This paper provides evidence of the feasibility and effectiveness of our proposed approach.
